Felt by 6 people across nearby locations.
On October 12, 2024 at 21:53 UTC, a magnitude 4.9 shallow crustal earthquake struck 2 km W of Coyuquilla Norte, Mexico, at a depth of 10.0 km and coordinates 17.3818°, -101.0773°. This earthquake was detected by 215 seismic stations with good location accuracy and was assigned a USGS significance rating of 371, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Mexico, a region characterized by the Middle America Trench, where the Cocos Plate subducts beneath the North American Plate. The nearest mapped fault system is the Middle America Trench. View all earthquakes in Mexico.
